HTTP 404 response on any resource group containing an Application Gateway resource

I've tried against multiple subscriptions and resource groups, they all seem to work except for resource groups containing Application Gateway resources. I get an HTTP 404 not found response, as seen below

Testing a little bit on my own, I get the same HTTP 404 response on the following uris
applicationGateways/[appgwname]/frontendIPConfigurations/appGatewayPublicIP?api-version=2016-09-01
applicationGateways/[appgwname]/backendAddressPools/[poolname1]?api-version=2016-09-01
applicationGateways/[appgwname]/backendAddressPools/[poolname2]?api-version=2016-09-01

I am also having the same issue, would love a fix!

Looks like the same issue on Load Balancers:

StatusCode: 404
ReasonPhrase: Not Found

Same issue here with a gateway.

I was able to reproduce the issue when Get-AzResource cmdlet in the function ConvertFrom-Network attempts to get network associations of the resources in current resource group, or the current context.

REASON: Often network associations as not limited to current Resource group and point to different resource groups and even subscriptions in many cases, and when Get-AzResource -ResourceId xxxxxxx cmdlet attempts to get the resource object of any such association, it fails because either it is outside current context or permission issues.

'Export-AzViz' cmdlet as of today only intends to target all resources within the target resource groups and there is no need to visualize dependencies or network associations outside the resource group. So, to fix this: Only target Resource IDs which has target resource group in the string, and skip all external associations, see the below lines of code to understand what has been implemented👇

At some later stage as and when this module evolves, I want to add a feature\enhancement to visualize any external dependencies as well, so creating another issue #58 and closing this one.

Can any one tell what could be the reason for this error.
